SAND-BAND FOR VEHICLES.

SPECIFICATION forming part of Letters Patent No. 319,522, dated June 9, 1885.

Application filed March 25, 1885. (No model.)

To all whom it may concern.-

Beit known that I, CHARLES H. SMITH, of Mount Pleasant, in the county of Henry and State of Iowa, have invented certain new and useful Improvements in Sand-Caps for Vehicle-Axles; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to an improvement in sand-caps for vehicle-axles.

Hitherto devices of various forms have been 7 employed to prevent sand, grit, 850., from working onto the axle-spindle from the inner end of the hub. These devices have been constructed, for the most part, to conform to some unusual arrangement of hub-attachin g devices or some peculiar construction of hub, and in the very few instances in which they have.

been constructed to meet the demands of hubs and axles of ordinary construction they have proved deficient, on account of being non-adjustable on the axle and their shape at the edge in contact with the hub.

The object of my present invention is to provide a sand-cap which may be used in connection with the axles and hubs of wheeled vehicles of ordinary construction, and which may be adjusted on the axles to take up wear, and which will present an edge in close proximity to the end of the hub, such that the sand and grit will be prevented from working in, and the wheel suffer no hinderance on account of the presence of the cap in close proximity thereto; and with these ends in view my in vention consists in a collar provided with a cupshaped flange, and secured in longitudinal adjustment on the axle by a set-screw or its equivalent.

My invention further consists in certain features of construction and combinations of parts, as will be hereinafter described, and pointed out in the claim.

In the accompanying drawings, Figure 1 is a vertical sectional view through the hub and sand-cap, and Fig. 2 is a perspective view of the same.

A represents the axle, B the/hub, and O the sand-cap.

The axle A' is here represented as an ordinary iron axle, rectangular in cross-section, and is provided at the inner end of the spin dle with an annular flange or collar, a, against which the inner end of the box I) abuts.

The inner end of the hub B is provided with a band, D, which projects more or less be yond the end of the hub.

The sand-cap 0 consists of a collar, 0, adapted to fit and slide on the axle, the said collar 0 terminating outwardly in the cupshaped flange O, which fits loosely within the recess formed by the extended portion of the band D. The exposed or convex face of the cup portion 0 continues from the collar 0 in an oblique position to the very edge of the cup, which rests in close proximity to the end of the hub; or it may have other forms a portion of the way; but it is important that it assume the oblique direction shown at c for a short distance back from the edge,

as it thus prevents dust and grit from lodging there and gradually working in between the cap and hub. The collar 0 is provided with a threaded perforation, o in which a set-screw, E, works and locks the cap to the axle in any desired proximity to the end of the hub by impinging against the axle.

The cap 0 is conveniently slid on the right and left sections of the axle before the same are welded together; but it may be made in two sections bolted together, or it may have a bore large enough to admit of its slipping over the flange a, and be provided with an elastic washer for taking up the play.

The cap as thus constructed forms no impediment in removing or adjusting the wheel,
